Hello, the question I have is does anyone know where the 4-pin plug is for the audio cable for the optical drive? I've looked all over the board and manual and can't find it. I'm wondering if there's something different that I need, because this audio cable came with my dvd drive, but I can't find where to plug it in on the motherboard, so I'm not sure what I have to do to get the audio from my optical drive. Please help me figure this out, thank you.
